  • Applications

    1,3-Dipalmitin is a saturated triglyceride with palmitoyl groups at the 1 and 3 positions. In industry it is commonly used as an emollient and base oil in cosmetics and personal care formulations, providing conditioning and a stable lipid phase; as a fragrance carrier in perfumery due to its inert, high-melting lipid matrix; as a processing aid and lubricant in plastics, coatings and inks to improve flow and processability; as a lipid-based excipient or carrier in pharmaceutical formulations for lipophilic drugs; as an intermediate in the synthesis of other esters and oleochemical derivatives; and as a reference material or internal standard in lipid analysis methods. Use is subject to regulatory constraints and formulation limits.
